Most solar water heaters cannot be directly converted to “electric water heaters” in the usual sense of the term.
Even though some have holes reserved for the installation of electric heaters, it is not cost-effective to use solar water heaters as pure electric water heaters.
Because the power supply line is long, it is a waste of electricity; the hot water is on the roof and the heat loss is significant, which is a waste of electricity.
If you really want to replace it with a purely electric storage water heater, it is recommended to scrap the original solar water heater, throw it away and completely reinstall the water heater electric storage.
Converting a solar water heater to an electric water heater requires the following steps: 1. Remove the collector tube and water tank from the solar water heater, then removewater and debris from pipes. 2. Install the electric water heater according to the electric water heater installation instructions. 3. Connect the water inlet pipe and outlet pipe of the electric water heater to ensure the connection is firm. 4. Connect the power cord of the electric water heater and turn on the power. 5. Turn on the electric water heater and wait for the water to heat up to the required temperature. It should be noted that the power and capacity of the electric water heater should be selected according to the household water consumption and should avoid water shortage or excessive waste of electrical energy.
